$4.6 million Merc heads $182 million Scottsdale mega-sales

As the sound of gavels – and jaws – dropping in Arizona recedes and the dust settles on a week-long £150million frenzy of classic car buying, it's time to take stock of the maddest auction extravaganza on the calendar.

Some stats:Six auction houses between them sold more than 2000 classic cars for roughly $182million, averaging $85,000 per car.

17 cars were sold for more than $1 million each.

Top-seller was the rare alloy-bodied 1955 Mercedes-Benz 300SL 'Gullwing' for an astonishing $4.62million. Gooding & Co also had the second priciest car when it raised just shy of £4million for a 1959 Ferrari 250GT California long-wheelbase.

By far the biggest sale total was Barrett-Jackson, which mustered $90million for its mammoth lot list of 1291 cars.

Highest 'per-car' sale rate was Gooding & Co, which amassed an average of $343,000 per car.

Loads of auction records were smashed, including the $2.9million that Barrett-Jackson took for a 1948 Tucker Torpedo.

Debutant Bonhams can go away happy with its results, too, having averaged nearly $150,000 per car and raised $5.7million from its 40 lots sold.
